Hitachi's new brand SimpleTech has a better way of keeping their external USB hard drive cool i.e using bamboo. Bamboo is thought to be able to dissipate heat more effectively by Hitachi. The bamboo-cooled external hard drive is called [re]Drive, which uses bamboo as the main heat sink and eliminates the need for fan to keep cool.

Since there is no fan, the [re]Drive aluminium enclosure saves power and does not make much noise excepts the little HD spinning sound. ¶Believe it or not, Hitachi also grows their own bamboo, so they can save more such as on transport.

The [re]Drive also features the turbo USB 2.0 interface which moves data 25% faster than the standard USB 2.0 connection. It measures 4.75 x 7.50 x 1.60 and costs $84 on Amazon for the 500GB version.
